The journalists are sure about the 2018 hurricane season. The scientists? Not so much.

I’m actually in Puerto Rico today for a conference on the situation here after Hurricane Maria. Since hurricanes are on my mind, I wondered what the forecast for this year looks like. As it turns out, the headlines give significantly different takes on what to expect. Here is a sample of news stories, all issued […]

One of most highly visible disputes arising out of the Trump Administration’s multifaceted efforts to roll back and nullify the natural resources policies of previous administrations is the decision by President Trump and Secretary of the Interior Zinke to substantially reduce two national monuments in Utah created by former President Obama under the Antiquities Act.

In the early 1990s, New York City began paying for land management in the Catskills watershed to ensure safe drinking water for the city, avoiding the cost of building an expensive water treatment plant.

Who should pay for the significant costs that cities and other local governments incur in responding to climate change? Los Angeles is the most recent city to explore the idea of suing fossil fuel companies for these harms, following in the footsteps of San Francisco, San Mateo County and a growing cohort of other jurisdictions […]

Human impacts on global natural systems are large and diverse

Climate change is well known now as a major impact of humans on the planet. But climate change is only one of a wide range of ways in which humans are dramatically changing natural systems at the regional, continental and planetary levels. For instance, greenhouse gas emissions are the driver of anthropogenic climate change. But […]

Human impacts on our planet will trigger changes in our legal system

Despite all the efforts at disinformation, the Trump Administration has let the truth slip out. On four occasions, the Administration has issued or signed warnings about climate change. One is an act of Congress. I’ll begin with the most recent and most significant example. Last Tuesday, Trump signed the Defense Authorization Act, HR 1810. The […]

As we have written previously, potable water reuse (recycling water to augment water supplies) is a promising way to diversify urban water supply portfolios. Direct potable water reuse (DPR), the injection of highly purified wastewater into drinking water systems, is among the newest, and most controversial, methods for augmenting water supplies. DPR is garnering increasing […]
